Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more clear and clear, the present invention will be further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the invention.
Please refer to fig. 1-10. The invention provides a vertical air conditioner, as shown in fig. 1, which comprises a shell 1, as shown in fig. 5, wherein an air inlet 2 and an air outlet 3 are respectively arranged on the shell 1, the air inlet 2 is positioned at the rear side of the shell 1, the air outlet 3 is positioned at the front side of the shell 1, and the air inlet 2 and the air outlet 3 are oppositely arranged; the casing 1 is provided with a containing cavity, as shown in fig. 5 and 6, a heat exchange assembly 4 is arranged in the containing cavity, and the heat exchange assembly 4 is used for carrying out heat exchange treatment on the air flow entering the containing cavity through the air inlet 2, such as heating cold air flow or refrigerating hot air flow; the heat exchange assembly 4 is close to the air inlet 2. The length direction of the heat exchange component 4 is set along the left-right direction, so that the air flow entering the accommodating cavity from the air inlet 2 can flow towards the air outlet 3 after passing through the heat exchanger.
As shown in fig. 5 and 6, an accommodating space 5 is formed between the heat exchange component 4 and the air outlet 3, an isolation component 6 is disposed in the casing 1, the isolation component 6 is disposed along a front-back direction, one end of the isolation component 6 is connected with the casing, the other end of the isolation component 6 can stretch back and forth to laterally isolate the accommodating space 5, when the isolation component 6 stretches and completely isolates the accommodating space 5 laterally, a left air duct 100 and a right air duct 200 are isolated in the accommodating space 5, the number of the air outlets 3 is several, a part of air outlets 3 corresponds to the left air duct 100, and a part of air outlets 3 corresponds to the right air duct 200; a through-flow air duct assembly is arranged in each of the left air duct 100 and the right air duct 200; one end of the isolation component 6 is connected with the casing 1, the other end is a free end, and the free end of the isolation component 6 is telescopic.
According to the invention, the free end of the isolation assembly 6 is telescopic, when the free end of the isolation assembly 6 is fully extended, the isolation assembly 6 can fully separate the left and right accommodating spaces 5 to form the left air duct 100 and the right air duct 200, one part of the heat exchange assembly 4 corresponds to the left air duct 100, the other part corresponds to the right air duct 200, and at the moment, if the cross flow air duct assemblies in the left air duct 100 and the right air duct 200 are opened, the vertical air conditioner can realize left and right air outlet simultaneously; if only one through-flow air duct component is opened, the vertical air conditioner achieves left air outlet or right air outlet. When the free end of the isolation assembly 6 is retracted, the left air channel 100 is communicated with the right air channel 200, and at this time, if one through-flow air channel assembly is independently opened, the heat exchanged by the heat exchange assembly 4 can flow to the through-flow air channel assembly entirely, so that when the left air channel 100 is communicated with the right air channel 200, the air outlet of only one through-flow air channel assembly is opened and is larger than the air outlet of one through-flow air channel assembly when the left air channel 100 is completely isolated from the right air channel 200.
As shown in fig. 2, 5 and 6, the isolation assembly 6 includes: a fixed plate 61, a separation plate 62, and a driving mechanism 63; one end of the fixed plate 61 is connected with the casing 1, the other end is connected with the separating plate 62 in a sliding way, and the position of the fixed plate 61 is fixed; the driving mechanism 63 is connected to the separation plate 62, and drives the separation plate 62 to slide back and forth relative to the fixing plate 61, and by sliding the separation plate 62 back and forth, the telescopic state of the whole length of the isolation assembly 6 is changed, so that the left air duct 100 is communicated with or isolated from the right air duct 200. When the driving mechanism 63 drives the separation plate 62 to slide away from the fixing plate 61 until the separation plate 62 contacts the casing 1, the fixing plate 61 cooperates with the separation plate 62 to completely isolate the accommodating space 5 from left and right; when the driving mechanism 63 drives the separation plate 62 to slide toward the fixing plate 61, the total length of the separation assembly 6 is shortened so that the left air duct 100 communicates with the right air duct 200.
The isolation assembly 6 is located at the center of the casing 1, as shown in fig. 5 and 6, in a preferred embodiment, the isolation assembly 6 is connected to the front inner wall of the casing 1, and when the free end of the isolation assembly 6 extends forward to contact the heat exchange assembly 4, the isolation assembly 6 completely isolates the left air duct 100 from the right air duct 200; when the free end of the isolation assembly 6 is retracted back and out of the heat exchange assembly 4, the gap between the isolation assembly 6 and the heat exchange assembly 4 communicates the left air channel 100 with the right air channel 200. Specifically, the fixing plate 61 is connected to the inner wall of the front side of the casing 1, the separating plate 62 extends toward the rear side of the casing 1, and the separating plate 62 is retractable in the front-rear direction. When the separation plate 62 extends backward and passes through the heat exchange assembly 4 and contacts the heat exchange assembly 4, as shown in fig. 5, the separation assembly 6 separates the accommodating space 5 from the left space and the right space to form left and right air channels, as shown in fig. 5 and 6, the through-flow air channel assembly 7 is arranged in the left air channel 100, the through-flow air channel assembly 7 is also arranged in the right air channel 200, the air outlets 3 are several, part of the air outlets 3 correspond to the left air channel 100, and part of the air outlets 3 correspond to the right air channel 200.
Indoor air enters the shell 1 from the air inlet 2 under the action of the through-flow air duct assembly 7, exchanges heat with the heat exchange assembly 4, and the air subjected to temperature rise or temperature reduction passes through the left air duct 100 and/or the right air duct 200 under the action of the through-flow air duct assembly 7 and then is blown into a room from the air outlet 3, so that air circulation is formed in the room, and the temperature of the indoor environment is regulated.
When the through-flow air duct assemblies 7 in the left air duct and the right air duct are started, after the air flow outside the shell 1 enters the accommodating cavity through the air inlet 2, under the guiding force of the two through-flow air duct assemblies 7, a part of the air flow enters the left air duct 100 through the heat exchange assembly 4 and is blown out from the air outlet 3 corresponding to the left air duct 100; a part of air flow enters the right air duct 200 through the heat exchange assembly 4 and is blown out from the air outlet 3 corresponding to the right air duct 200. The two through-flow air duct assemblies 7 are started at the same time, so that the flow rate of the air flow passing through the heat exchange assembly 4 is greatly improved, the air output is improved, and the indoor environment temperature regulation efficiency is improved; meanwhile, the left air duct 100 and the right air duct 200 are respectively corresponding to the air outlets 3, so that the air outlet range is increased, the noise is reduced, and the efficiency of the vertical air conditioner on indoor environment temperature adjustment is further improved.
Further, when the separation plate 62 is retracted forward, the separation assembly 6 loses the complete separation effect on the accommodating space 5, so that the left air duct 100 is communicated with the right air duct 200 near the side of the heat exchange assembly 4, and at this time, the air flows passing through the left side and the right side of the heat exchange assembly 4 can flow toward the left air duct 100 and the right air duct 200. When the separation plate 62 is in the retracted state, if the through-flow duct assemblies 7 in the left air duct 100 and the right air duct 200 are opened simultaneously, both the left air duct 100 and the right air duct 200 can discharge air; if only the through-flow air duct assembly 7 in the left air duct 100 is opened, only the left air duct 100 will exhaust air; if only the through-flow duct assembly 7 in the right duct 200 is opened, only the right duct 200 will be blown.
In the preferred embodiment, when the user is located on the right side of the vertical air conditioner, the isolation assembly 6 is adjusted to be in a retracted state, and the through-flow air duct assembly 7 in the left air duct 100 is opened, so that the left air duct 100 is air-out, and the user is prevented from opening the air-out direction; when the user is located at the left side of the vertical air conditioner, the isolation assembly 6 can be adjusted to be in a retracted state, and the through-flow air duct assembly 7 in the right air duct 200 is opened, so that the air outlet of the right air duct 200 is realized, the user can avoid the air outlet direction, and the user experience is improved.
According to the invention, through the adjustment of the telescopic state of the isolation assembly 6 and the adjustment of the opening state of the through-flow air duct assembly 7, the simultaneous operation of multiple air ducts is realized, the air output is improved, the indoor environment temperature adjustment efficiency is improved, the independent operation of a selective single air duct can be realized, the air output direction is adjusted according to the position of a user relative to the vertical air conditioner, the direct blowing of the air flow to the user is avoided, and the user experience is improved.
In the second preferred embodiment, as shown in fig. 8 and 9, the isolation assembly 6 passes through the heat exchange assembly 4 and is connected to the rear inner wall of the casing 1, the free end of the isolation assembly 6 is disposed forward, and when the free end of the isolation assembly 6 extends forward to contact the front inner wall of the casing 1, the left air duct 100 is completely isolated from the right air duct 200; when the free end of the isolation assembly 6 is retracted back out of the cabinet 1, the gap between the free end of the isolation assembly 6 and the cabinet front side inner wall communicates the left air duct 100 with the right air duct 200. Specifically, the rear end of the fixing plate 61 passes through the heat exchange assembly 4 and is connected to the rear inner wall of the casing 1, the front end of the fixing plate 61 is slidably connected to the separating plate 62, and as shown in fig. 8, when the separating plate 62 extends forward to contact the front inner wall of the casing 1, the separating assembly 6 completely separates the left air duct 100 from the right air duct; as shown in fig. 9, when the separation plate 62 is retracted rearward to be separated from the front side inner wall of the cabinet 1, a gap occurs between the separation plate 62 and the front side inner wall of the cabinet 1, so that the left air duct 100 communicates with the right air duct 200.
As shown in fig. 2 and 4, the fixing plate 61 is provided with a chute 611, the length direction of the chute 611 is set in the front-rear direction, and one end of the chute 611 facing the heat exchanger is provided with an opening, and the separating plate 62 is inserted into the chute 611 through the opening and slides back and forth along the chute 611. The sliding groove 611 plays a limiting role on the sliding of the separating plate 62, so that the separating plate 62 can slide back and forth along a linear direction, and thus the separating plate 62 can contact the casing 1 when extending forwards or backwards, and the isolating assembly 6 can separate the accommodating space 5 from left and right. In addition, the chute 611 serves to accommodate the separation plate 62, and when the accommodation space 5 is not required to be isolated from the left and right, the chute 611 can accommodate the separation plate 62, and when the through-flow duct assembly 7 in a single duct is opened, the airflow flowing in the accommodation space 5 will not directly act on the separation plate 62, and will not affect the separation plate 62, thereby improving the stability of the installation of the separation plate 62 in the accommodation space 5.
As shown in fig. 3, the driving mechanism 63 includes: a motor 631 and a gear 632. Preferably, the motor 631 is disposed at the bottom of the fixing plate 61, and a rotating shaft of the motor 631 extends vertically downward and is fixedly connected to a central hole of the gear 632, so as to drive the gear 632 to rotate along a horizontal plane; the central axis of the gear 632 is disposed in the vertical direction and perpendicular to the sliding direction of the separation plate 62. Further, the separation plate 62 is provided with a rack 8, the rack 8 is meshed with the gear 632, and the gear 632 rotates to drive the rack 8 to move back and forth, so as to drive the separation plate 62 to slide back and forth.
As shown in fig. 3, the rack 8 is located at the bottom of the separating plate 62, the bottom of the separating plate 62 extends downward beyond the chute 611, and the rack 8 is located outside the chute 611, so that friction between the rack 8 and the inner wall of the chute 611 is avoided when the separating plate 62 slides into the chute 611, and abrasion of the rack 8 is caused.
The top of the fixed plate 61 is provided with a mounting plate 9, and the mounting plate 9 is connected with the top of the casing 1; the mounting plate 9 is located above the chute 611, a gap is arranged between the mounting plate 9 and the chute 611, a limiting block 10 is arranged at the top of the separation plate 62, and the limiting block 10 is located in the gap; the width of the stopper 10 is greater than the width of the chute 611, so that the separation plate 62 is mounted on the fixing plate 61 through the stopper 10. The mounting plate 9 not only has a fixed mounting function on the fixing plate 61, but also has an up-and-down limiting function on the limiting block 10 by being matched with the sliding groove 611, so that the vertical movement of the separating plate 62 is avoided, and the mounting stability of the separating plate 62 in the accommodating space 5 is ensured.
The heat exchange assembly 4 comprises a heat exchanger 41 and electric heaters 42 symmetrically arranged on the front side of the heat exchanger 41; the length of the heat exchanger 41 extends from the left air duct 100 to the right air duct 200; two of the electric heaters 42 are respectively located in the left air duct 100 and the right air duct 200. When the indoor environment temperature is lower, the user can start the vertical air conditioner to heat, if the indoor environment temperature is lower than a set value, the electric heater 42 can be started, and the heat exchanger 41 and the electric heater 42 work cooperatively, so that the indoor environment temperature can be improved quickly, and the user experience is improved.
As shown in fig. 5, the through-flow air duct assembly 7 includes an impeller 71 and a guide wall 72, and the isolation assembly 6 and the guide wall 72 are respectively located at two sides of the impeller 71 and form a guide channel 13. When the impeller 71 is started, under the guiding action of the isolation assembly 6 and the guide wall 72, the air flow passing through the heat exchange assembly 4 can directly flow towards the air outlet 3, so that the air outlet force of the air outlet 3 is improved.
A left air deflector 11 and a right air deflector 11 are arranged in the diversion channel 13, and the left air deflector 11 and the right air deflector 11 are positioned at one end of the diversion channel 13 facing the air outlet 3; the air guide channel 13 is internally provided with an upper air guide plate 12 and a lower air guide plate 12, the upper air guide plate 12 and the lower air guide plate 11 are sequentially arranged along the air outlet direction of the air guide channel 13, namely, the upper air guide plate 12 and the lower air guide plate 12 are positioned on the inner sides of the left air guide plate 11 and the right air guide plate 11, when the left air guide plate 11 and the right air guide plate 11 are opened, air flows through a plurality of gaps between the upper air guide plate 12 and the lower air guide plate 12 and through the up-down swinging of the upper air guide plate 12, the air flows are adjusted in the up-down direction before passing through the left air guide plate 11, and accordingly the air supply angle is increased under the cooperative guide effect of the upper air guide plate 12 and the left air guide plate 11 and the right air guide plate 11. Meanwhile, the air flow is cooperatively guided by the guide wall 72 and the isolation assembly 6, so that the air flow passing through the impeller 71 can be directly blown to the air outlet 3, the air beam is more concentrated, and the air flow is guided by the upper and lower air deflectors 12 and the left and right air deflectors 11.
